Here is one example. On July 22, 2002, Attorney General John Ashcroft announced that the government would now be enforcing a 50-year-old regulation requiring immigrants to report changes of address within 10 days of moving or face a $200 fine or up to 30 days in prison. Such a status violation could also make the offender subject to deportation.
According to the Immigration and Naturalization Service, the rule applied to some 11 million people, including foreign nationals who enter the US on temporary visas, students, green card holders, asylum seekers and refugees. The rule had not been previously enforced because it led to such an avalanche of forms that it was seen to be unworkable.
